法律研究Python Pandas - 获取指定周期的年周
要获取给定周期中的年周，请使用 period.weekofyear 属性。首先，导入所需的库 −
import pandas as pd
pandas.Period 表示某一个时间段。创建两个 Period 对象
period1 = pd.Period("2020-09-23")
period2 = pd.Period(freq="D", year = 2021, month = 4, day = 16, hour = 2, minute = 35)显示 Period 对象
print("Period1...\n", period1)
print("Period2...\n", period2)从两个 Period 对象获取年周
res1 = period1.weekofyear res2 = period2.weekofyear
示例
以下是代码
import pandas as pd
# The pandas.Period represents a period of time
# creating two Period objects
period1 = pd.Period("2020-09-23")
period2 = pd.Period(freq="D", year = 2021, month = 4, day = 16, hour = 2, minute = 35)
# display the Period objects
print("Period1...\n", period1)
print("Period2...\n", period2)
# get the week of the year from two Period objects
res1 = period1.weekofyear
res2 = period2.weekofyear
# Return the week of the year from the two Period objects
print("\nWeek of the year from the 1st Period object ...\n", res1)
print("\nWeek of the year from the 2nd Period object...\n", res2)输出
这将生成以下代码
Period1... 2020-09-23 Period2... 2021-04-16 Week of the year from the 1st Period object ... 39 Week of the year from the 2nd Period object... 15
